symbol not found grub_os_area_addr

[Dabaizki]

My ubuntu 10.10 cannot boot from disk .
only can boot from >grub rescue
and I type these
>grub set root=(hd0,1)
>grub set prefix=(hd0,1)/boot/rub
>grub insmod normal
>grub normal
enter

Boot menu is back,but it dosnot work.
So i press C to command line
and type these
>grub root (hd0,1)
>grub linux (hdo,1)/boot/vmlinuz-2.***
【Symbol not found: 'grub_OS_area_addr'】
>grub initrd (hd0,1)/boot/initrd-2.***
【Symbol not found: 'grub_OS_area_addr'】
>boot

It dosnot work at all.
how to solve it?

Thanks.

Thank you , for that quick reply. It‘s useful for me.

and I just make a USB Ubuntu livecd to reinstall ubuntu to my backup partition sda4.

when it restart , "Ubuntu 10.10 on sda1 "is aviable on boot menu.

thanks.

But i still confused by the grub location.sda? sda1?
